SYPH Series Dry Extruder – Product Introduction
1. Equipment Overview
The SYPH series dry extruder is a high-performance, versatile feed processing machine engineered for the dry extrusion of various grains, including corn, soybeans, cottonseed, and rice bran. Covering a power range of 7.5–160 kW and delivering processing capacities from 50 to 2,600 kg/h, this equipment is specially developed for baby animal feed production and other deep-processing applications.
Unlike wet extrusion systems, the dry extruder operates without the need for external steam or water addition, offering a simpler, more cost-effective solution for feed processing. It is widely adopted by feed mills, intensive farming operations, and feed deep-processing enterprises seeking reliable, high-quality output with low operational complexity.
2. Core Product Advantages
Engineered with precision mechanical design and advanced wear-resistant technology, the SYPH series dry extruder effectively resolves common industry challenges, including poor material adaptability, rapid part wear, operational instability, and high maintenance costs. Seven core advantages deliver efficient, stable, and low-consumption production:
1. Broad Adaptability & Optimized Extrusion Performance
Equipped with a comprehensive range of interchangeable extrusion screws and pressure rings, the system can be flexibly configured to match specific material characteristics and process requirements. This ensures optimal expansion and consistent product quality across a wide variety of raw materials.
2. Multiple Discharge Modes for Product Versatility
Three optional discharge configurations—single-hole, multi-hole, and annular gap—allow for rapid product shape changes without replacing the main machine. This design greatly enhances production flexibility, simplifies changeovers, and expands the range of finished products.
3. Ultra Wear-Resistant Components for Reduced Operating Costs
Core wearing parts, including the extrusion screw and pressure ring, are manufactured from premium wear-resistant alloy steel using specialized processing technology. Their service life exceeds that of conventional materials by more than 5 times, significantly reducing replacement frequency, maintenance costs, and production downtime.
4. Anti-Bridging Design for Uniform Feeding
The feeding system incorporates a variable-pitch screw that effectively eliminates material bridging, caking, intermittent flow, and blockages. This guarantees continuous, homogeneous, and stable feeding, supporting 24/7 uninterrupted production while minimizing material waste.
5. Variable-Frequency Drive for Precise Feed Control
Equipped with an advanced inverter-driven feeder, the extruder offers simple operation and highly accurate feed volume adjustment. Real-time control allows precise synchronization with production capacity and material conditions, adapting seamlessly to varying output demands while delivering notable energy savings.
6. Integral Casting for Enhanced Operational Stability
The bearing box features an integrated cast structure and is precision-machined using high-accuracy CNC boring equipment, achieving superior coaxiality and concentricity. This results in reduced vibration and noise, smoother machine operation, a lower failure rate, and extended overall equipment lifespan.
7. Imported Bearings with Active Lubrication & Cooling
Core transmission components are fitted with original imported NSK precision bearings, supported by a dedicated oil lubrication and cooling system. This active thermal management extends bearing service life by 3 to 5 times compared to standard bearings, ensuring reliable performance under sustained high-load, continuous operation.
3. Application Effects (Key Processing Results)
| Raw Material | Processing Effect |
|---|---|
| Soybean | Urease activity index (UA value) ≤ 0.2, fully meeting feed safety standards. |
| Corn | Starch gelatinization degree reaches ≥ 98%, significantly improving digestibility. |
| Cottonseed | Detoxification rate reaches ≥ 95%, effectively reducing free gossypol content. |
| Rice Bran | Lipase activity is effectively inhibited, and the fat layer structure is destroyed, achieving stabilization for extended storage and further processing. |
